Value for money
Extremely fast delivery. Received the Sim card in 2 days. Network is very stable and fast. £10 for a 30G plan is value for money.

Generally a good experience
Generally a good experience although was strange that I was advised to port number away to a different company to switch plan and then port back. Port took nearly a week longer than advised times.

Switching to Mozillion was incredibly straightforward. I ordered my SIM online and it arrived the very next day. The process of porting my old mobile number over was smooth, with no issues at all. I love that I can keep track of everything via their online account, making it a stress-free experience. Highly recommended for anyone wanting a quick switch

Great price for the service on one of the best weeks

Tested it for one month
1. Extra Charge: I tried Mozillion for one month. They tried to charge me two months fee for one month use.
2. Lousy Service: very poor indoor signals. They say that if you go over your data limit, your speed will just be reduced, but instead, you end up with no data at all.
3. 5G signal and speed are acceptable.

Hello, thank you for your feedback. All one month rolling plans require 30 days notice to cancel as per our standard terms.
Regarding signal, our network covers 99% of the UK population - we do have a Coverage Checker available on our site so you can check Mozillion indoor and outdoor coverage.
Your data allowance resets each month and if you do need more data, you are able to purchase a data add-on from within your Mozillion Dashboard.
